To all whom, t may concern. f

Be it known that I, FRED L. SIMON, a citizen of the United States,residing` at rBaltimore, in the State of Maryland, haveinvented certainnew and useful Improvements in Conveyers; and I do hereby declare thefollowing to be a full, clear, and exact description of theinvention,`s'uch as' will enable others skilled in the art to which itappertains to make and use the same.

My invention relates to conveyers. Among the objects of my invention areIo provide a portable conveyer which can purpose of'stacking goods intiers.

To provide a portable conveyer comprising carrying fingers whicliarespaced apart, said fingers being arranged uponr endless chains whichform the conveying element so that said carriers can be introducedbeneath a platform composed of spaced `apart'load-` ing bars having buta slight elevationy fromk the floor. y n

By the Iattainment of this object, I avoid the heretofore necessaryoperationof lifting the article to be transported to a considerableheight so that lingers could be moved thereunder in order to engage saidarticle. n

To provide a simple, cheap, lightand portable conveyer which canbe'adaptedv for the transporting of objects having@variousy shapes bysimply changing the shape `of the carrier or the platform, or both.y nThese and further objects of my invention will be set forth in thefollowing specificar tion, reference being had to the accompanyingdrawings, and the novel means by which said objects are eifectuated willbe definitely pointed out in the claims.

In carrying out myinvention Iv make'use ot' the instriunentalitiesillustrated inthe accompanying dra\vin,gj:--` n i Figure 1 is a sideview` partly in section, of a conveyer constructed according to myinvention. n

Figure 2 is an enlargedview of'some of the parts shown in Figure 1lookingin the direction of the arrowv 2 in said Lligure.

Figure 3 is a section along the line 3 in Figure 1 looking in thedirection of the arrows.

Figure 4 is an enlarged detailed view of parts hereinafter referred to.

In the drawings 10 represents a boom which is composed of channel ironssuch as 11 which extend `'from the slidey Aa.

end kto end of said boom for the purpose lof` NrofFFICE; i

guiding the conveyer rollers12. 'The chany nelirons llare spaced apartand maintained in correctr relative fposition by lat-tice Work such as13 andnear each end of said boom a plate such 'as 14 1s secured. In theplates'14 there areprovided bearing'for theshafts 15 j and 16. y Theshaft 15 is mounted in housingsv such as 17 which are supported upon thecarriage 18. The carriage 18 is mounted upon a pairof Wheels such as 19(anda castor 20.

A guide 21 is pivoted as at 22-to the carriage liand a slide 23, pivotedat 24 to a plate 25 secured to the boom, slidesfreely within the guide21. Aliand orpowe'r operated Winch f,

2Giis mounted upon the yguide 21and connected by a rope to the hook 27'secu1ed to Saidiwinchis for the purpose of raising or lowering the boomA10 in order to deliver the articles to" any height desired ashereinafterexplained.` IVhen the boom 10 is raised to theproper heightitis maintained in the said position by the engagement fof the lpawl 28with the' ratchet wheel 29.

` Pivotally mounted as at 30 upon each side yof the carriage 1S nearoneend thereof are' a pall otleversl, the lower ends of `which y rarepivotally connected to aflange*provided `at the sides of the supportingpla-te 32. A

knut is swivelled'in any approved manner at',

the upper endofeach of the levers 31 and a screw 33 isthreaded'in saidnut. Saldscrew turned Aend 37.

Sprocket LWheels 38`and" 39 lare rigidly mounted uponthe shafts 15 and16. A pulis revolubly supported by bearings 34 and yis "revolved ahandle y The supporting 1 plate 32 carries a plurality of loading bars36, each of` which is, provided .WithdanupY 'by' the electric motor orother 'source of vpower 43 through the intermediary of thereductiongearing 44a. Sprocket'chains such I as 44 extend the length ofthe boom 10 yand y around the Wheels 38and 39. A plurality of shaftssuchjas 45 vis secured to said sprocket chains and Vthe rollers 12 arerevolubly mounted `on the ends ofsaid'shafts thus serving to support thechain i between cthe Wheels 38and39.; f

At Whatever j portion of thejchains 44 Iit is desired to attachycarrying fingersfsuch as 46, tivo! of the shafts 45 'are locatedcloseto;

gether, a plurality of links 47 is mounted f be noted that the bars 36are so located that y the lingers 46 will pass between same. One of theoutermost fingers 46 carries a tappet 50` which is located to strike thecam 51 formed upon the boomlO for a purpose hereinafter explained. y Y

Any desired plurality of the rollers 12 'may be grouped adjacent thefingers 46 in order that the shafts 45 may supportthe weight of thearticle 52 that is being transported and a chain such as 53 has one ofits ends connected to one of said shafts and the other end connected toone of the fingers 46. Only one tappet 56 and one chain are shown in thedrawings but itr is to be noted that more can be used if desired.purpose hereinafter,explained latches such as 54 are revolu'bly mountedupon the shafts 45 and ysaid latches are arranged to engage pins such as'55 which are mounted in the ends of one of the outside lingers 46. Eachlatch is providedV with a tappety 56 located to be struck by the pin 57which is secured to the boom 10. y

A chute 5Scomposed of a plurality of-bars located similarly to ythe bars36 so thatthe finO'ers 46 can )ass therebetween is riOfidl secured tothe arm 59 and the latter is pivoted as at 60 to thebooin 10. A brace 61is pivoted as at 62 to the arm 59 and there is swivelled inthe end ofthe ybrace 61 the screw 6?,"which is threaded in the nut 64; The nut 64is swivelled upon the boom 16 and is turned -by the handle 65.

' The operation of my improved conveyer is as follows The operator turnsthe yhandle 85 so as to move the levers 3l in a clock-wise directionAthus lifting the supporting plate 32 from the floor. The carriage 18can thenbe wheeled to yany position desired.

The oper-alor then applies power'. to the winch 26 and raises or lowersthe booni 10 so as to place the chute 58 in the proper location for thedelivery of the articles where desired. rlhe operator then drops thepawl 2S to maintain the boom `in said position. y

The operator then turns the' handle65 in such a direction as to bringthe plate' 32 in contact with the floor. He then starts theinotor43 anddelivers the articles upon thetop of the bars 36 as shown atthe left ofFigure 1L It isto be noted that', in thus delivering the articles theupturned ends 37 locate the articles in correct position to be actedupon by the fingers 46.

v VAs the chains 44 move in a direction of the y'arrow 5 on. the underside of the boom r16 For "a they bring the tappets 56 against the pin 57thus removing the latch 54 from the pin 55 and allowing the fingers .46to drop upon the plate 32 between the bars 36. The continued mot-ion ofthe chains 44 then moves the fingers 46 end-wise between'said bars vandbetween the article to be carried and plate 32. Asthe chains 44 movearound the wheel 155 the-chain 53 becomes taut and lifts the fingers 46through thebars 36 into contact with the article and then carries thearticle on the upper sidev` of the booin 10 until it slides from theconveyer when the chains 44 move around the wheel v239. Then the articleSlides from the conveyer it drops onto the chute 58, and the latter bymeans ofthe adjustable brace 61 may be set at any angle to deliver thearticlewhere desired.

After the article drops from the conveyer onto the chute 56 the fingers46 mayy or may not drop of theirl own weight, but in any case the tappet50 comes into Contact with the cam 51 and said fingers are movedupwardly until the'pin 55 engages the latch 54.

The fingers 46 then move on the under side of the boom 10 in thedirection of the arrow 5 until the latch is unlocked and saidv fingersagain engage the plate 32.

Thus it will be seen that I provide a conveyer capable of being readilytransported from place to place 4and capable of piling articlesin tiers.

It is further to benotedv that by; arrangi ing the ngers 46 to have aneiid-wise movement between `the bars 36 y it becomes lunnecessary tolift the articles to ajconsiderable lie-ight from the floor in order tobring themv into operative relation with the conveyer as has heretoforebeen necessary. This improved result l obtained by the end-wise motionofthe fingers46 witlireference to the bars 36. y

It is to be noted that the winch 26 is merely representative of anymeans for elevating or depressing the booni 10. The motor 45:3 and themechanical connections for revolving the vsprocket wheel 15 arerepresentative of any source of power and an;7 form of connectiontherefrom to said wheel.

`While I have shown one forni of mechanism for elevating and depressingthe plate 32, and one form of mechanism for controllingfthe operation ofthe fingers 46, it is to be understood thatthese mechanisms have beenshown and described for illustrative purposes only and in no wise tollimit the scope of my` invention for many changes may be made thereinwithout departing from the spirit thereof.
